Additional information

As the substance poses no hazard to aquatic organisms, and consequently not to the various environmental compartments (freshwater, marine water, STP, sediment (fresh and marine water), soil, air, predators), no classification is warranted.


Aquatic acute toxicity

48 h, EC50 (Daphnia magna): > 100 mg/L (nominal concentration)

72 h, ErC50 (Raphidocelis subcapitata): > 100 mg/L (nominal concentration)


Aquatic chronic toxicity

72 h NOEC (Raphidocelis subcapitata): 100 mg/L (nominal concentration)

Based on read-across from the source substance biodegradation study: not readily biodegradable: 1 % (based on % CO2 evolution after 28 days OECD 301 B)

Partition coefficient: log Kow = -2.36 at 20 °C


Classification according to CLP

The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was found to be not readily biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the toxicity test to algae. This study revealed a 72 h EC50 of > 100 mg/L and the 72 h NOEC of a toxicity to alga and cyanobacteria test with the test substance was determined to be 100 mg/L. Based on these results, the substance is neither classified as short-term (acute) aquatic toxicity nor classified as long-term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Commission Regulation (EU) 2020/1182.
